Abstract (en)
[origin: EP0417695A2] A suspension control system for controlling an suspension (S0) having a shock absorber (M1) provided for each wheel of a vehicle includes a damping force change rate detector (M2) which detects a damping force change rate (V) indicating a rate of change of a damping force of the shock absorber, and a damping force controller (M3) which alters the setting of the damping force on the basis of a relationship between the damping force change rate and an adjustment reference value (Vref). The system also includes a road surface condition detector (M4) which detects a condition of a road surface on which the vehicle is running on the basis of a change of the damping force of the shock absorber. Further, the system includes a damping force adjustment correcting unit (M5) which corrects the adjustment reference value by learning the adjustment reference value on the basis of a parameter (N) related to the damping force of the shock absorber which reflects the condition of the road surface.
